Question

Select the mathematical sentence that is true.
(Points : 4)
3 (7 3) + 5 < 6 + 2 1

3 (7 3) + 5 6 + 2 1

3 (7 3) + 5 = 6 + 2 1

3 (7 3) + 5 > 6 + 2 1

Answer 1

3(7?3)+5<6+2?1
3(7?3) + 5 ? 6 + 2?1
3(7?3) + 5 = 6 + 2 ?1
3(7?3) + 5 > 6 + 2 ?1

Answer 2

somethings are missing where the question marks are

Answer 3

sorry. those are where the minus signs are supposed to go

Answer 4

all of them are subtraction signs?

Answer 5

Think its A?

Answer 6

yes they all are subtraction

Answer 7

in that case i would go with D
3(7-3) + 5 > 6 + 2 -1
21 - 9 + 5 > 8 - 1
13 + 5 > 7
18 > 7 <-true

Answer 8

since 18 is greater than 7 right?

Answer 9

4x 3 5 (Points : 4)
{1, 2}
{3, 4}
{2, 3, 4}
{1, 2, 3, 4}





Question 7. 7. Determine which value

Answer 10

last one^

Answer 11

can you be a bit more detailed 4x ? 3 ? 5

Answer 12

4x -3 > 5

Answer 13

between 3 and five theres a line under >

Answer 14

oh ok

Answer 15

4x - 3 > 5
+3 +3
4x equal to or greater than 8
4x >_ 8
4(1) = 4 not eqaul to or greathan than 8
4(2) = 8 so its equal to 8
4(3) = 12 so its greater than 8
4(4) = 16 so its greater than 8
What is the answer?

Answer 16

4x equal to or greater than 8

Answer 17

these are the answers {1, 2}
{3, 4}
{2, 3, 4}
{1, 2, 3, 4}

Answer 18

yes i know, but what do you think is the answer, we had to replace x for 1 then 2 then 3 then 4 to see which makes the inequality true. I did the work and gave the answers. See which of 1,2,3,4 replacing x makes the inequality true

Answer 19

what makes the inequality true is which of 1,2,3, and 4 multiplied by 4 is equal to or greater than 8

Answer 20

oh

Answer 21

i did the work, see which is greater than or equal to 8, its that easy

Answer 22

ok whats the answer?

Answer 23

{3, 4}

Answer 24

A - {1, 2}
B - {3, 4}
C - {2, 3, 4}
D -{1, 2, 3, 4}

Answer 25

theres one more
remember greater than or EQUAL to 8

Answer 26

{2, 3, 4}
